Moderated poster sessions, plenary sessions and IC courses over time. This represented great progress. In addition, articles on IC were increasingly included in Urology, Journal of XAV-939 mechanism of action urology and other prestigious journals; supplements to these journals were devoted exclusively to IC, as were books and monographs. Urology Times published numerous articles on IC. In 1999, for the first time, IC was included in the standard review course for urology residents who planned on taking their urology boards. Epidemiology How did we prove that a large number of people have IC and that it was not a rare disease? Epidemiology was the answer. Historically, IC was considered to be a rare post-menopausal condition in elderly women, with perhaps 45,000 estimated cases. The very first Epidemiology Study conducted on IC in the United States was published in 1988 by Dr. Philip Held and his team at the Urban Institute. NIDDK also provided some support. Critical to legitimizing the disease, Dr. Held and his team found that: (I) For every one patient diagnosed with IC in the urologist’s office, five went undiagnosed; (II) It took an average of 4.5 years and five doctors to achieve a correct diagnosis; (III) IC patients scored worse than patients undergoing renal dialysis on `Quality of Life’ questionnaires; (IV) A total of 60 of patients reported pain with sexual intercourse, many so severe that they abstained altogether; (V) By combining medical expenses incurred by an IC patient with lost wages because of disability, Held’sstudy calculated the economic impact of the disease to be as high as 1.7 trans-4-HydroxytamoxifenMedChemExpress trans-4-Hydroxytamoxifen billion per year. Since that time, several epidemiological studies have been published. The Rand Corporation Interstitial Cystitis Epidemiology study (RICE study) by Sandra Berry et al., published in 2011, estimated that 3.3-7.9 million women in the U.S. have IC/PBS. The authors believe, however, that this is a substantial underestimation. “Symptom severity and impact were comparable to those of adult women with established diagnoses. However, only 9.7 of the women reported being assigned a BPS/IC diagnosis.” Berry et al. estimated that 2.7 to 6.5 of women in the United States have urinary symptoms consistent with a diagnosis of IC/BPS (5). Konkle et al. concluded that (The Rand study) “strengthen(s) the existing body of evidence which suggests that this condition is substantially burdensome, and likely underdiagnosed and undertreated in the United States.” (6). Clemens et al. evaluated data from the BACH study (Boston Area Community Health Survey) published in 2007, and concluded that between one and four million men have IC in the U.S. (7), which is much higher than previously thought. There is now no way to dispute that IC/BPS exists, with so much data to back up the numbers. These epidemiological studies confirm that there are many more men and women who have IC/BPS in the U.S. than previously thought. Although there are many more women than men who suffer from this condition, the original ratio of 9:1/female to male in the older literature may be overstated.
